RESUMO
Sounds are important sensory cues for food perception and acceptance. We developed and validated a large-scale database of kitchen and food sounds (180 stimuli) capturing different stages of preparing, cooking, serving, and/or consuming foods and beverages and sounds of packaging, kitchen utensils, and appliances. Each sound was evaluated across nine subjective evaluative dimensions (random order), including stimuli-related properties (e.g., valence, arousal) and food-related items (e.g., healthfulness, appetizingness) by a subsample of 51 to 64 participants (Mdn = 54; N = 332; 69.6% women, Mage = 27.46 years, SD = 10.20). Participants also identified each sound and rated how confident they were in such identification. Results show that, overall, participants could correctly identify the sound or at least recognize the general sound categories. The stimuli of the KFS database varied across different levels (low, moderate, high) of the evaluative dimensions under analysis, indicating good adequacy to a broad range of research purposes. The correlation analysis showed a high degree of association between evaluative dimensions. The sociodemographic characteristics of the sample had a limited influence on the stimuli evaluation. Still, some aspects related to food and cooking were associated with how the sounds are evaluated, suggesting that participants' proficiency in the kitchen should be considered when planning studies with food sounds. Given its broad range of stimulus categories and evaluative dimensions, the KFS database (freely available at OSF ) is suitable for different research domains, from fundamental (e.g., cognitive psychology, basic sensory science) to more applied research (e.g., marketing, consumer science).
RESUMO
ABSTRACTMemory is a reconstructive process that is prone to intrusions and distortions. These processes can be amplified by the emergence and propagation of false information in the social environment. While the acceptance of misinformation is well documented in individual memory tasks, the production of false memories in social interaction contexts presents mixed findings. One factor that may contribute to these inconsistencies is the collaboration method used, which may vary in the opportunities they offer for more (free-for-all) or less (turn-taking) discussion. The current study contrasts these two collaboration methods in misinformation acceptance. Participants watched a video, followed by an individual recall task. Then, they completed a questionnaire containing true and misinformation about the video, individually or in pairs (using free-for-all or turn-taking methods). Finally, participants were given a new individual recall task. Results revealed that participants responding to the questionnaire using the free-for-all method were more accurate and accepted less misinformation (vs. turn-taking and individual conditions). Critically, in the second individual recall, these participants also recalled less misinformation from the questionnaire than those in the turn-taking condition. These results suggest that discussion opportunities during social interaction enhance correction and error-pruning and reduce misinformation acceptance.

Resumo Este trabalho consiste numa revisão teórica com o objetivo de enquadrar historicamente o modo como as falsas memórias têm sido estudadas. Embora a maior parte dos estudos sobre falsas memórias tenha sido realizada a partir da última década do século XX, os primeiros datam do final do século XIX. Assim, e com o objetivo de assinalar os grandes marcos históricos na investigação das falsas memórias, começam por apresentar-se os estudos pioneiros realizados ainda no século XIX, bem como as pesquisas realizadas sobre o efeito das perguntas nos relatos de crianças e adultos. Posteriormente, apresentam-se as primeiras pesquisas realizadas com o objetivo específico de estudar o efeito de perguntas sugestivas no aparecimento de falsas memórias, seguidas dos estudos que recorreram a uma abordagem naturalista tendo-se tornado decisivos para a compreensão deste fenômeno. Já na segunda metade do século XX, ganha peso uma abordagem mais cognitivista no estudo deste fenômeno, e surgem os paradigmas da desinformação e DRM, que serão também discutidos. Ao longo do texto, reflete-se também sobre os mecanismos que foram considerados como estando na base do aparecimento das falsas memórias, bem como sobre as implicações científicas e sociais deste fenómeno.

Abstract This work consists of a theoretical review with the aim of historically framing the way false memories have been studied. Although most of the studies on false memories have been developed since the last decade of the 20th century, the earliest is dated from the late 19th century. With the aim of pointing out the great historical milestones in the research of false memories, the pioneering studies carried out in the 19th century, as well as the researches on the effect of the questions on the reports of children and adults, are presented. Subsequently, we present the first researches carried out with the specific objective of studying the effect of suggestive questions on the production of false memories, followed by those who used a naturalistic approach and become decisive for the understanding of this phenomenon. In the second half of the 20th century, a more cognitive approach takes place, and the paradigms of misinformation and DRM arise, which will also be discussed. Throughout the manuscript, it is also reflected on the mechanisms that were considered to be the basis of the production of the false memories, as well as on the scientific and social implications of this phenomenon.
RESUMO
RESUMO Após anos de pesquisa sobre o funcionamento da memória humana como um processo de armazenamento e recordação individual de informação, surgem cada vez mais estudos focados na compreensão da memória como um processo também vivido em grupo: a memória colaborativa. Nesse sentido, o presente artigo pretendeu, através de uma revisão da literatura, sintetizar algumas das questões mais relevantes do estudo da memória colaborativa. Para tal, apresentamos o paradigma experimental mais usado nesse tipo de estudos, bem como os custos e benefícios que resultam da partilha e recordação de informação em grupo. A redação deste artigo permitiu-nos concluir que, apesar do número crescente de estudos nessa área, ainda existem algumas lacunas, nomeadamente no que se refere à produção de falsas memórias, bem como acerca da real implicação prática do uso de diferentes tarefas de memória.
ABSTRACT After years of research on the functioning of human memory as an individual process of retention and retrieval of information, currently an increasing number of studies is appearing focused on the understanding of memory as a group process - collaborative memory. This paper aims, by means of a literature review, to summarize some of the most relevant issues raised about the study of collaborative memory. To accomplish this aim we present the most frequently used experimental paradigm in collaborative memory studies, as well the costs and benefits that arise from sharing and retrieving information in group. The redaction of this article has enabled us to conclude that despite the growing number of studies in this area there are still some gaps, particularly with regard to the production of false memories, and in relation to the actual practical implications of using this type of tasks.
RESUMO
A sugestionabilidade infantil é influenciada pela capacidade de memória, idade ou desejabilidade social. Este estudo teve como objetivo estudar estes fatores em três grupos de crianças com idades de 5/6 anos, 8/9 anos e 10/11 anos. Para tanto procedemos à construção de uma escala de avaliação da sugestionabilidade infantil baseada na Escala de Sugestionabilidade de Gudjonsson (GSS; Gudjonsson, 1997). Os resultados obtidos revelaram que as crianças mais novas foram as mais sugestionáveis, fenômeno que parece estar associado ao elevado grau de desejabilidade social das suas respostas. Relativamente à memória fonológica, verificamos que a sua menor amplitude esteve também relacionada com maior sugestionabilidade infantil. Sugere-se que as variáveis memória e desejabilidade social sejam cuidadosamente consideradas no momento de obtenção do testemunho de crianças. (AU)
Children's suggestibility is influenced by several factors such as memory, age or social desirability. The main objective of this study was to analyze how these factors are associated with the degree of suggestibility in 5/6 year-old, 8/9 year-old and 10/11 year-old children. For a suggestibility measure, a new scale based on the Gudjonsson Suggestibility Scale was developed (GSS; Gudjonsson, 1997). Results showed that: younger children are more suggestible than older children; a higher degree of social desirability is associated with stronger suggestibility responses; and a smaller memory span is related to greater children's suggestibility. Conclusions highlight that memory and social desirability should be analyzed carefully when eyewitness accounts of children are considered. (AU)
